The American Transportation Research Institute (ATRI) is a nonprofit research partner of the American Trucking Associations. Since 2002, ATRI has partnered with the trucking industry to continuously collect GPS data on key national corridors, using data from nearly 1 million heavy-duty trucks in North America. Currently, ATRI collects more than 100 million GPS data points per day. The data is collected from wireless onboard communication systems used by the trucking industry and can be used to provide important insights into freight activity.
